Abstract: Abstract It is  intended  that a  control device  for a hydraulically operated consumer (1) be improved.  It can be supplied with pressure fluid on the upstream side by a pressure fluid source (3) by way of a pressure compensating valve (5), a connecting conduit (11), an upstream valve (7) and an upstream consumer conduit (12).   A signal conduit (18) is at a signal pressure (PS), which acts on the pressure compensating valve (5) in the same sense as a spring (28) and opposite to a compensating pressure (PK) tapped from the connecting conduit  (11).   The  signal conduit (18) comprises a first connecting branch (19) connected to the upstream  consumer  conduit  (12),  a  second  connecting  branch  (20) connected to  the  connecting  conduct  ( 11 ), and  a  third  connecting branch (21) connected to the return conduit (16).  To form a pressure dividing arrangement (26), each connecting branch contains a throttle (22, 23, 24).  In this way, the initial operation can be very rapidly stabilised whilst retaining substantial independence of the supply.            Fig. 1

Abstract: ABSTRACT OF THE DISCLOSURE:      A rock ring for a rock breaker having an impeller mounted on a vertical axis.  The rock ring is formed to retain a quantity of rock in which the flow of material from the impeller creates a rock race. The rock race is formed in a "sling-like" shape by means of spaced rock race control members.  Primary rock race control members are placed more closely to the impeller than secondary rock race control members.  The method of breaking is primarily by a flow of rock from the impeller table which result in mid-air collisions with a counterflow of rocks which flow from the rock race in the rock ring.

Abstract: Abstract of the Disclosure A manual entry keyboard system for data processing with as few as twelve keyswitches produces enough entry signals for direct alphanumeric input of sequential characters, one character per finger stroke of a single finger at high speeds from a single hand in a touch typing mode.  A live keyboard is particularly adapted for use with modern data processing systems for an effective high speed manual interface compatible with their comprehensive capabilities by changing live key-switch modes for direct entry in numeric calculation, alphanumeric data processing and the like modes.  To further improve accuracy of manual keyboard input, (1) the reach of the fingers from home keys in touch typing position is reduced, (2) the data is entered with few operator mental decisions where errors are more frequent, (3) different key locations are touch coded by keyboard tactile elements such as depression, textured and ridge contour configuration on a keyboard surface to produce operator touch feedback, (4) the keyswitches must be moved to input data thereby to permit finger rest on the keys without error and to provide to the operator feedback of signal completion by the switch movement feel, (5) the key-switches are located side-by-side in a single field for compact use on pocket sized version with advantages of maximizing the number of selections and reducing errors by reduction of the reach from a home key position, and (6) the keyswitches conform to natural hand geometry for more comfort and reduced errors.  A twelve key symmetrical telephone type matrix will provide full alphabetic capability as well as numeric and thus can serve by itself to replace PBX type telephone switchboards while processing numeric signals in a conventional manner.

Abstract: DECELERATION AND PRESSURE SENSITIVE PROPORTIONING         VALVE WITH HIGH PRESSURE DAMPING    ABSTRACT OF THE DISCLOSURE A proportioning valve assembly  (10,  210)  in  a housing (12,  212)  is pressure responsive to control the flow of fluid to a wheel brake cylinder.  The proportion-ing valve (20, 220) is connected to a fluid channel (31, 231) opening into a reservoir (13,  213), a second valve (34,  234)  being  disposed  in  the  channel  (31,231)  and being  engaged  by  an  inertia  sensitive ball  (40,  240) located either on a ramp (17) or within a recess (235) of the second valve (234).  The ball (40) is responsive to deceleration of the vehicle and moves up the ramp (17), or  the  ball (240)  moves  multi-directionally  from  the recess (235) to be both longitudinal and lateral deceler-ation responsive.  Movement of the ball (40, 240) permits the second valve  (34,  234)  to close and prevent  fluid communication between the fluid reservoir  (13,  213)  and the proportioning valve  (20,  220)  in order to vary the outlet pressure of the proportioning valve  (20,  220)  in response  to deceleration  or  cornering  of  the  vehicle. The  proportioning  valve  (20,  220)  includes  a  second piston (80, 280) which has a plunger end (82,  282) that extends within the channel (31, 231) and a bore (303) of a sleeve (301).  The sleeve (301) has an orifice (307) to restrict fluid pressure flow from the bore  (303) around the plunger end (282) and through the orifice (107,  307) to  the  channel  (31,  231).   The  sleeve  (301),  orifice (307),  and  plunger  end  (82,  282)  provide  damping  of second  piston  when  sudden  high  pressure  applications occur,  and  thereby  eliminate  the  occurrence  of  wheel lock-up.

Abstract: ABSTRACT     An apparatus automatically controlling the temperature of welding bands used to weld plastic films or the like comprises a dividing circuit for determining the temperature of the welding band in dependence on the out-put voltage and current of the heating circuit and a controller for controlling the output power of the heating circuit in dependence of the deviation of the determined actual temperature of the welding band from a predetermined desired value.   The output voltage of the dividing circuit, which output voltage is an analog voltage representing the high-temperature resistance of the welding band, and an analog voltage representing the low-temperature resistance of the welding band, are applied as input voltages to a second dividing circuit, which generates an analog voltage representing the quotient of said two input voltages of said second dividing circuit.  Said output voltage is multiplied in a multiplying circuit with the output voltage generated by an analog adder as the sum of an analog voltage representing the low-temperature at which the low-temperature resistance of the welding band has been measured and an auxiliary analog voltage, which represents a calculated auxiliary temperature.  A first subtracting circuit is provided for subtracting the auxiliary voltage from the output voltage of the multiplying circuit and for generating an analog voltage which represents the actual temperature of the hot welding band.  A second subtracting circuit is provided, which generates a differential voltage representing the difference between the analog voltage representing the determined actual temperature of the welding band and the analog voltage representing the predeter-mined desired temperature of the welding band and applies said differential voltage to the controller.  The apparatus can simply and quickly be adjusted to match the welding band employed and in particular after a replacement of a welding band can simply and quickly be adjusted to match the possibly different dimensions and composition of the new welding band.

Abstract: ABSTRACT            A LOCK MECHANISM AND A SPRING AND CAM ASSEMBLY THEREFOR     The lock mechanism has a spring and cam assembly provided for returning the lock plunger assembly of the mechanism from a locked to an unlocked position thereof.          In addition, however, the spring and cam assembly carries an enlongated limb.  When the lock plunger assembly is translated to a locked position, it forces the limb to extend from the spring and cam assembly to a disposition in which it blocks a knob catch which is carried in the outside spindle of the mechanism.  Accordingly, for being blocked by the limb, the knob which is latchingly engaged by the catch, cannot be removed from the outside spindle whenever the mechanism is in its locked disposition.  The spring and cam assembly comprises a compact unit which is slidably received in the outside spindle and confiningly supports the limb therewithin for extension therefrom into obstruction of the knob catch.
